L'UBlRICATOR FOR RAILWAY JOURNAL Y .Application Vled August 21, 1926. Serial No. 130,618.

This invention relates to lubricators for railway journaljboxes and the like.

j An objectv ofl the invention is lto provide a lubricator of this character which can readily be inserted into and withdrawn from a standard railway lcar journal box, and one which at the same nomical to build,v which is rugged and n ot easily gotten out of order, and which will provide constant and ample lubrication for the journal under which it is placed. y

Heretofore it has been common practice to pack these journal boxes withrwaste and oilY andA to depend upon ythe capillaryl action of the waste to carry the necessary oil to Y the 'j ournal'.

' The present invention replacesthat crude method of lubrication more efcient and economical and which requiresmuch less laboi` and inspection to keep it in proper working order. This and other objects as will hereinafter appear are accomplished by this invention which is fully described in the following V`w1th roundedlongitudinally disposed leaf Y .y

The lubricator has a hollow body lO'which is relativelydeep at the outer end and shalf time is'slmple and eco-` by one which is muchv low at the innerend` 11 so as make 'it readily insertable into the journal box. This hollow body is covered with'wool felt or the like 12 whichjishe'ld thereon vin lany suitaround it and lsecuredin place by means of screws 14. Q v` l. g

Two spaced longitudinally disposed barsv 15 areV yieldably carried on springs 16.

' able manner as -by means of a strap 13 passed When the lubricator is in place'in the jourf nal box thesefbars'press the felt cover k12v against the bottom* of `the journal 0.? It j will be understood, of course, that the weight through the journal brass VB1 las shown in Figs. 1 and 2. A sponge, wool or the like 17 is placedk in the bottom ofthe lubricator' l so vas to carry oil therein to the felt 12 with f lof the car is transmitted to the journal C Y of hinged lids 19 which are normally held closed'by means of springs'20. Y f

The body of the lubricator isV provided .springs 21 which are secured at the inner end by means ofscrews or rivets l22;` the outer end preferably bearing upon the bottom of the hollow body 10,`but free to` slide thereon.

' Afspring 23 lis also secured tothe innerfend the journal boxhousing lwhile at the upperV i corners are provided notches'or the like 27 which are adapted to engage pins28 which* extend outward from the forward `end of the lubricator body. A screw 29 is then insertedethrough the support 25' .to fasten itxto the lb'ricator body 10 to prevent 'it from becoming dislodged therefrom. K

Y To remove the '-lubricator' j from the jour*-` nal box as-shown in Figs. 1 and 2, the opera-V lui) tor lifts upon the journal'box Vcover B2', j

swinging it about'the pin B3 until he has ac-l cess to the inside of the journal box. VHe' then reniovesfthe screw 29, at the same timev llifting upon the outer end -of Lthe lubricato'r body while pressing Vdown on' one` end of until one of the notches 27 the Support 25 can be swung clear of the pin 28. The other ,notch 27 is then freed from its pin 28 Y. in the sam-e way after whichgthe support is removed from the journal box. operator then depresses the outer end of the lubricato-r body so asto bring the shoulder' 8O below the bottom of the collar C1 Von the outer end or" the journal C. He' then reaches in with one Vhand on each side of the journal and depresses the inner end of the lubricator body, f ilattening springsy 21l and 23 at'the lsame-.time slipping the lubricator body around underthe collar C1. The shape of the` body as shown, being deeper at the outer end than at the inner, facilitates this movement at the-sametime forming a'resen Voir of ample size for oil.

To insert-the lubricator into the journal l box, exactly the opposite of this operation is performed, the lubricator body being in'- serted beneath the 'journal C, the springs 21 and 23 pressing it up against the bottom of the journal, the shoulder on thellubr'- cator fitting in back of the collar C1A 'so as to n y proper position on the journal. It will be understood, of course, that vthe lubricator will be somewhatshorter than thev` bearing portion of. the journalv so as to peranitthe necessary endwise play of the journal. With the lubricator body in this position, the support 25 is then inserted and securedf by means 01? the screw 29. Oilmay then be added 'through either the channels 18 until thesevv channels are substantially insure its f full tothe top,- the feltg12 serving toretain the. oil: exceptl where-the felt comes in. con# y ing, but it Awill be understood thatuthis de tactvpwith the bottom of the journal C.

VThus., it will be seen that the lubricator body is pressed upwardly toward the jour-r nal, by means of the springs 21,23,` and 26, while the lubricator body itself. is held away from the journal by the-actionof the springs'. 16, so that the lubricator bodyI is virtually. floatingy between these-'two sets of springs.which` materially lessens the danger of breakage `dueto they severe road shocks and pounding -Iwhich are always incident to akrailway journal. The side springs 34 take theside thrust of the bearing.

-Byf` the use of two spaced bars 15, pressure is applied to the felt cover 12 att-Wo points leaving a somewhat depressed portionv oity the cover therebetween which acts to catch and hold oili Thus anainple-supply of oil is suppliedfor the bearing, the cleanliness of the oil being insuredfbythe fact that it is kept within the reservoir in the body 10 to which no grit and dirt is able to find its way due to the felt covering 12 andy a tight fastening thereon.

,It desired7 those portions of thecover 12 which are not incontact Vwiththe journal may be treated in any desired manner so as to render them impervious to oil so. as to further insurethe seepage of the oil The y through the cover except where the lubricant is desired.`
